ARIA Container Tabindex Error

  • מאמר

Text

Element is a focusable container with active descendants defined but without tabindex value greater or equal to 0.

Type

Error

Description

This error applies to elements that have the aria-activedescendant attribute, are not disabled, and do not have the tabindex attribute set to a value that is greater than or equal to 0. These elements must be in tab order because they are responsible for handling keyboard events for their child elements.

To fix this error, set the tabindex attribute to a value that is greater than or equal to 0.

Example

HTML 
<div role="listbox" id="listbox1" tabindex="0" aria-activedescendant="listbox1-1"> 
       <div role="option" id="listbox1-1" class="selected">Item 1</div> 
       <div role="option" id="listbox1-2">Item 2</div> 

       <div role="option" id="listbox1-3">Item 3</div>
      ... 
<div>
